Since so many new members here often have questions on the different optics options available to them, I thought I’d post some pics of the various optics set ups I’ve used in the past or am currently using.
If you have a variation not posted yet, by all means post a pic with a description of what optics/BUIS combo your running. Magnified optics are also welcome, not just CQB types. For those not familiar with the term “co-witness” here is an explanation. AR-15 • Optics, Mounts, and Sights • The big bad BUIS FAQ ***Photos removed.

As a newbie to the AR15 community, this kind of information with pics is indispensible. Thanks so much to everyone involved in it and especially to QUIB for starting the thread.

Your welcome! I had started a similar thread a few months back but it fizzled out and didn’t get much response. So, I thought I’d try again. There are so many options and variations when it comes to optics, I thought pictures and descriptions of what some of us are running might be of use. I’m glad some of you find it helpful. |

If this gets big enough I would vote the thread for tack worthy.

www.mountsplus.com/miva/merchant.mvc?page=MSP/PROD/arms-rings/22HIGH Are the 1" inserts a good idea? |
|
|
Yes its a 22M68 with full spacer, and they both cowitness in the lower 1/3. |

|
What is the height of the full spacer (flat top to top of spacer), 1/2 or 3/4 inch? |

|
Looks like 3/4 to the top of the spacer. |

Thanks so much to all who have taken the time to post pics. It would be nice to try and keep this thread going, so many new guys out there unsure about which direction to go with their optics, I‘m sure seeing what‘s out there in use could help them out.

Yes, It needs to be tacked Good going QUIB |

I have a couple stupid question here. My rifle has a RRA upper with a flip up front sight and detachable tactical carrying handle. Sitting in my safe waiting is a EOTech 552 which I plan to mount on a Surfire M73 handguard, which I am waiting on deliverly. Attached are a couple pics of the upper alone.
http://i74.photobucket.com/albums/i271/Ginsu69/IMG_0196.jpg http://i74.photobucket.com/albums/i271/Ginsu69/IMG_0195.jpg 1st Q: Does it matter if I mount my EOTech that far forward? 2nd Q: When using the EOTech, do I need to have my front sight flipped up? Mounting the EOTech on the tactical carrying handle give absolutely no co-witness and will not work there. Thanks from the optics newbe Rob |

Here's a question for the Faithful: Which is preferred, absolute co-witness or a lower 1/3 witness?
To my way of thinking, each has advantages and disadvantages. An absolute co-witness allows a very low sight mount. In theory, at least, that's good for accuracy since you're likely to maintain a solid cheek weld on the stock. The only serious disadvantage I see is that if you use a fixed rear BUIS you may be distracted by the somewhat busy sight picture. I'm pretty sure I would. A lower 1/3 witness avoids that busy sight picture, but the sight is mounted somewhat higher to achieve that result. Does this sound reasonable? |

Mounting the EOTech on your hand guards is a matter of personal preference, many folks have this set up. The problem I see you running into is the ability to co-witness. The RRA Tac Handle was designed with the Aimpoint in mind. Mounting an Aimpoint to the Tac handle with a x-wide low ring would provide a co-witness. Mounting the EOTech on the Tac handle will not provide you with the ability to co-witness. Mounting the EOTech on the hand guard, the Tac handle will block the EOTech widow due to the Tac handles height. My suggestion is to sell the Tac handle and go with a good folding rear BUIS. |

Absolute or lower 1/3rd co-witness are again both a matter of personal preference. Your theory on co-witness is absolutely correct. In my pics on page one you will see my EOTech/CCH combo. This set up was as you described, “too busy” for me. A riser of some type that provided a lower 1/3rd co-witness might have helped but I planned on eventually swapping the EOTech for an Aimpoint and decided to continue shooting as is. |

Thanks QUIB! I thought that was my most reasonable solution my problem. At the time I ordered my upper, the pics on RRA website looked like the fixed rear on the tac handle was taller and I was also unsure of what optics I wanted at the time. Yesterday when I got my EOTech and did a test mount I was disappointed with the outcome. Last night I set my EOTech onM4 handguards and it looked as though my plan may work, but I do understand that what I layed out and what the actual results can be totally different. So with that all being said, I have shopped and i think I may go with the Wilson Flip up rear BUIS unit, which appears to give me the ability to have elevation control to go along with windage. I was really hoping that I would not have to spend more money but I guess so.... Thanks again. |

No problem! Since you have your EOTech now, what you might try just for shits n’ giggles is to mount your EOTech as far forward as possible on your upper receiver. Next using the front mount only from your RRA Tac Handle, mount it to your upper behind the EOTech. Now take a peek through the optics. This will give you a better idea of what your up against mounting the EO to your railed HG’s. A little bit more stable than just placing the EO on top of the HG’s and holding it there by hand. I think I’m correct in stating that the SF railed HG’s are a bit higher than the upper receiver but still not high enough to over come the height of the Tac Handle. If I’m wrong, someone please correct me. |

This thread is very valuable to any beginner, lets get a sticky on this plz.
|
|
could you happen to be able to tell me where to get the mount to put the docoptics ontop of the acog? |
|
|
I'm a traditionalist meaning absolute cowitness for me.
BTW, this thread is worthless without STICK-PICS. ETA: J/K Quib . Thanks for another outstanding thread. |
